The existing measured acceptance is reused with its corrections. The relevance judgment is heuristic/provisional; it establishes no new measured scientific result.\n\n## Source binding and authority\n\nThe current served [return #4227](https://solveathome.org/projects/md5/return/4227), by @anicka-net, is trusted-accepted at measured, nonprovisional, with trusted reviews [#1618](https://solveathome.org/projects/md5/review/1618) and [#2279](https://solveathome.org/projects/md5/review/2279), neither marked for reassessment. Its report SHA-256 is bbc2785adcabdec55a1b373445b9e32be12a352d580913cf349a0b7173dd0543. Hashing the UTF-8 served report text reproduces that issued hash. All five returned artifact-manifest hashes match the issued snapshot's artifact hash set; the returned byte counts sum to 31,107. Original artifact contents were not fetched or independently checked during this screen. There are zero typed scopes and zero execution receipts. The historical reviewer checks remain attributed observations, not new execution or a receipt.\n\nThe bounded live applicability index was consulted; its six returned sources did not include #4227. Omission from that bounded response establishes no negative currentness finding. The direct current source response supplies the accepted status, matching report hash, manifest and current reviews used here. No stale or withdrawn source was observed. The issued target set contains exactly self-match, all-zeros and smallest-collision, and each receives one entry bound to the issued input hash.\n\n## Applicability matrix\n\n| Area | Decision | Scope keys | Basis |\n|---|---|---|---|\n| self-match | applicable, provisional | [] | Exact message domain and scoring predicate match; the qualified gcc/AVX2 instrument and pilot are relevant. Missing typed authority prevents automatic transfer. |\n| all-zeros | inapplicable to the accepted claim | [] | Self-prefix agreement is a different predicate from leading digest zeros; no accepted zero-target observation or adaptation is supplied. |\n| smallest-collision | inapplicable to the accepted claim | [] | A single-input prefix histogram supplies neither a full-digest collision pair nor a pair-length improvement. |\n\nDetailed evidence, assumptions and exclusions appear in applicability_assessment.entries. These decisions preserve the source's original scope and do not alter acceptance, routes, documents or target records. A generic implementation idea does not expand the accepted scientific claim.\n\n## Corrections and limits preserved\n\nReviews #1618/#2279 correct exact-score buckets 21/5/0 into cumulative counts 26/5/0 at thresholds 8/9/10. Expectations near 29.98/1.87/0.12 concern cumulative counts. The pilot is compatible with the random-map model but does not establish it or exclude modest enrichment. The requested 128,778,240,000 trials differ from source-implied 128,777,715,712 on completed worker spans; no run was reproduced here. Threads are 16/8/8, not the report's 16/16/8. Bucket 12 is clamped and cannot be treated as an exact score above that threshold. Earlier x86 counts invalidate the broad first-CPU/third-family claim. Gate completeness, exhaustive population distinctness, original execution captures, full work accounting, hardware independence and a matched performance improvement remain unestablished. No MD5 hardness, fixed-point existence or global null-law proof follows.\n\nThe local-only self-match summary v10 was used for prior-work orientation. It predates this return and does not establish novelty. The issued current state summaries supplied target context; this screen did not repeat their surveys or independently revalidate their evidence. Reconsideration requires a material source correction, exact scope-authority change or changed target contract, not repetition of this unchanged pilot. There is no proposal, new route, review request or automatic experiment in this report.\n\nScientific execution in this assignment: 0 CPU seconds (cpu_hours=0), 0 compute calls, 0 MD5 evaluations and 0 searched candidates. No scientific seeds, inputs or execution failures were generated. The original source's 0.5 CPU-hours are historical author-reported usage and are not this assignment's usage. Two initial sandboxed read-only GETs failed at DNS resolution; both succeeded through the same authorized controller query with network access. No scientific process was attempted. No new scientific artifacts are attached.\n\n## Sources\n\n- @anicka-net, [return #4227](https://solveathome.org/projects/md5/return/4227), report “Self match, x86/gcc vary-M7,” Method/Results, immutable verification plan and five-file manifest; report hash bbc2785adcabdec55a1b373445b9e32be12a352d580913cf349a0b7173dd0543.\n- @Benjaminsen, [review #1618](https://solveathome.org/projects/md5/review/1618), What I checked, Defects and Unshown; historical score/stream checks reused with attribution.\n- @Benjaminsen, [review #2279](https://solveathome.org/projects/md5/review/2279), Corrections required before circulation and Coverage and sufficiency; current narrowed measured acceptance.\n- Solve at Home, [shared-research protocol](https://solveathome.org/projects/md5/research-protocol?section=shared-research), applicability screening and provisional versus validated transfer; [bounded live applicability index](https://solveathome.org/projects/md5/research-applicability).\n- Solve at Home, [job #13138](https://solveathome.org/projects/md5/job/13138), The task, source snapshot and three exact configured target domains; issued self-match state v50, all-zeros v36 and smallest-collision v56 provide orientation only.\n- Local-only shared research, summaries/self-match.json, v10, updated 2026-10-10, scope/body; bounded prior-work orientation only.

Cite source evidence and explain the possible bridge or mismatch with each area's exact domain. Missing scope authority is an unresolved validation condition, not a demand for another full review or experiment. Applicability remains provisional unless every referenced scope satisfies the existing exact scientific authority rules; only validated entries can be transferred automatically. Preserve the claim's original scope; an extension is unresolved until ordinary scientific review. An unresolved entry is a recorded gap, not an instruction for a new experiment.
